IMPROVE!) SPRING-BED BOTTOM.

The Schedule referred to these Letters Patent and making part of the sem.

Teelt persons to whom these presents may come:

Be it known that I, TYLER Hows, of -Cambridge port, in the county of Middlesex, andr State of` Massachusett-s, have invented a' new and useful Improvement in Spring-Bed Foundations; and l-I do hereby declare the same to be fully described in the followingspecification and .represented in theaccompanying drawings. i i

Figure lis a topV view of a .bed-bottom provided with my invention Figure lis au uiidel-side view thereof; Figure Bis a perspective view ot? one of the wire springs; and

Figure Ltris a side view of lone ofthe slats.

.My invention has reference4 to that class ofbedfoundations in 'which each of'rthe slats `is supported upon springs arranged near its two ends, and consists in so forming and applying the springsA to their snpportinghars andthe slats as not only vto form a strong and durable conneotiombut produce an easy, elastic, and .yielding ibundation'for a mattress, and at the same time afford a ready means of either connecting the slats with their springs or disconnecting them therefrom, as may be desirable.

In the said drawings AA denote the side rails of the bed-bottom, which are connected by means of two cross-bars B' B.

ThroughV each of thefsaid cross-bars I make a' series of holes, (two in numberfor each slat,) andl at adistance apart equal to or a littlegreat-er than vthe width of `the slat, each pair of holes being to receive the two arms a af of a spring, C.

The saidholes I bore onV the inner side of each ci' the cross-bars, 'and extend them downward at au angle of forty-'five degrees or thereahouts, so ,as to cause them to terminate on the-underside oi' the said bars.

`I next take pieces of Vspring wire of the propel' diameter and, length and bend the same into a rectangular shape,.the base or connected end b of each having a length Acorresponding to the width of a slat or ea'clrtwo of a pair of holes in upward and curved over, and partially around the cross-bars,.the backfand top edges of which are rounded. The projectingend of each ot' the wires is'next' V bent inwar'dtoward each other, and at right ang-les to the remaining portion, so as to forma journal or support, c c', for the slats, the samebeing as shown in tig. 3, or the said ends may be so bent as to form an acute angle with the remaining portion,if desirable, in which case the holes, made in the slats to receiv'e Vthem should have a corresponding pitch or in, clnation.

' The arms of the said springs do not rest in contact with .the curved 4surface of the cross-bars with which they are connected, but are curved to the are of a. circle of much larger radius, sopas to allow of their springing inward and have a lsucieut, degree of I elasticity to prevent them from becoming set' under any ordinary amountofpres'snre brought to bear vupon the slats with which they are attached. y D D, Sto., denote the slats of y the bed-bottom, they 'being made of wood, `and extending nearly the entire length of thc bed foundation.

Eachof' the said slats has two'holes d d formed in each4 side of it,and near the'ends thereof, the same being to receivethe bent ends or extremities c c ot' the springs, which, when connected therewith, as

showuin the drawings, maintain the sl'at suspended at both its opposite edges.

I would remark that I- do not limit Inyself.to arranging 'the holes in the cross-bars 'in the slanting direction, as described, as the said holes may be bored vertically through the said bars; but I consider .the first-mentioned method to be th'e better one, asV the springs are notso' liable to be broken or injured by a lateral strain at their vpoints rif-egress on side of the crossbars.

In applying the slats-to the springs, we have simply to press apart the arms-ot' the latter and linsert the journals or parts c c' in the sockets of the slats, and then press or restore the arms to their normal position. The elastic force ofthe wire will then maintain them in irm connection.

I o release the slats, we have only to withdraw the journals `or parts c c from their sockets. i

By'my" peculiar construction of the springs, and their application to the cross-bars and the slats, I gain several important advantages over manyof the bed-bottoms in the market:

- In the first place, the springs are so constructed nand--arrangcd as not to come in contact with a mattress or bed when placed upon the slats. l

Second. mattress is supported throughout its entire length, and'dees not sag at either of its ends.-

rlhird. .lhe springs are so applied'to the crossbars as to prevent accidental detachment; land Fourth. The slats can be readily detached from the bed-'bottom or applied Vthereto whenever it may be desirable.

the under I do not claim, broadly, supporting; the slats of a. B B', the two series of springs C C, formed as debed foundation upon springs arranged near the ends scribed, and the series of slats C', arranged and apof such slats and attached, to the cross-bars thereof, plied together substantially asv hereinbefore specified. nor ldo I claim any of the devices shown in either of TYLER HOWE. t-lie patents numbered 57,720, 69,198, or 78,825,218 my invention diiers therefrom.

I claim my improved spring-bed bottom as composed of the frame or rails A A, the two cross-bars Witnesses:
